The tool below keeps revision inside your own notes.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Land based empire terms, from your own notes
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it.

Paste a passage and the rules return cards from it. The course outline is invisible to the tool, so completeness is decided before you press the button.
Guns opened the ground, administration held it
Field armies built around cannon and massed muskets let these states expand faster than neighbours could adapt. That part is settled and briefly stated. The graded part is what happened the morning after: how a court in one capital extracted grain, soldiers and obedience from provinces weeks away. Every high scoring comparison lives in that second question.
Staffing: how to run a state without arming your rivals
The Ottomans levied boys through the devshirme and trained them into Janissaries and ministers who owed everything to the sultan. The Qing kept banner forces distinct from Han officialdom. The pattern beneath both is identical: build an elite whose loyalty points up, because it has no independent base below.
Revenue: an empire is a machine for collecting the harvest
The Mughals ranked officers as mansabdars and collected through zamindars who kept a share of what they gathered. Delegated collection scaled across a subcontinent, and the same delegation later leaked power to the collectors. Name the mechanism and then name its cost; that pairing is what comparison prompts are fishing for.
Legitimacy is built, and each empire built it differently
The Safavids made Twelver Shia Islam a state identity. Ottoman sultans paired a Sunni caliphal claim with the image of the lawgiver. Qing emperors patronised Confucian ritual while guarding Manchu distinctness, and Russian tsars leaned on the Orthodox church. Monumental architecture did the same argument in stone for subjects who would never read a decree.
The comparisons the exam actually asks
Prompts pair two empires against one problem: recruitment, revenue or belief. The move that scores is naming the shared problem first, then the two different tools, then one consequence of the difference. The Safavid and Ottoman pairing carries an extra edge because the religious split turned an ordinary rivalry into a border that still matters.

What years does AP World Unit 3 cover?
1450 to 1750, the period the course calls land based empires.
Which empires does the unit compare?
Ottoman, Safavid, Mughal, Qing and Russia, with the Songhai and others appearing as supporting examples.
Why are they called land based empires?
Their wealth ran through land, harvests and the peasants who worked them, and the maritime empires of Unit 4 exist to make that contrast.
How much detail do I need per empire?
One staffing tool, one revenue mechanism and one legitimacy claim per empire covers nearly every comparison the exam can ask.
What makes the Ottoman and Safavid rivalry examinable?
The Sunni and Twelver Shia split turned a border war into an identity conflict, which lets questions connect belief, statecraft and war in one prompt.
Can I build questions from my own Unit 3 notes?
Yes. Upload the chapter as a PDF or photograph the pages, and every question comes from those pages rather than from the wider syllabus.
